Description
Technical field
The present invention relates to structural part of automotive chassis technical field, and in particular to a kind of automotive towing arm body stiffening panel.
Background technology
Towing arm as connection vehicle body and chassis important component in vehicle travel process between vehicle body and chassis
Coordination plays a key effect.Automobile can run into various complicated travel conditions, such as in form on road：Accelerate, turn, stop
Car and excessively hole etc..Under these driving cycles, road surface can produce very big impact of collision load to wheel, if the peace of towing arm
It is unreasonable to fill supporting structure design, often causes towing arm mount point nearby or support produces fracture in itself, and then may make
Into the running out the way even failure such as overturning, life danger is brought to passenger.
Towing arm is connected by mounting bracket with longeron, because longeron thickness is relatively low, it is difficult to meet mount point intensity requirement,
Therefore it is provided with reinforcing plate inside many vehicle body join domains.What more patents concentrated solution at present is the mounting bracket being connected with vehicle body
Structure, and ignore interior of body reinforcing plate Structure Designing Problem.In fact the quality of internal reinforcing plates structure, is dragged directly affecting
Arm body mounts intensity is draged, as fruit structure is weaker, connection is inconsiderate, may directly result in towing arm mount point and be unsatisfactory for by force
Degree requires, and then causes mount point sheet metal component cracking nearby, influences the security of vehicle traveling.
The content of the invention
The purpose of the present invention is to propose to a kind of intensity for strengthening towing arm mount point, and it is reliable to improve towing arm mounting structure
The automotive towing arm body stiffening panel of property and security.
The automotive towing arm body stiffening panel of the present invention, key are that the both sides of the automotive towing arm body stiffening panel are set
There is side flanging, the front-end and back-end of the automotive towing arm body stiffening panel are respectively equipped with front end flange and rear end flange, described
Between rear end flange and a side flanging be provided be used for longeron inwall welding First Transition flange, the rear end flange with it is another
The the second transition flange for being used for strengthening plate weld with threshold, the rear end flange, side flanging, First Transition are provided between side flanging
Flange, the second transition flange integrally connected.
The automotive towing arm body stiffening panel of the present invention, by increased reinforcing plate turnup structure, add reinforcing plate with
The contact area of side cover plate and threshold reinforcing plate, so as to improve the support stiffness of whole automotive towing arm body stiffening panel, and it is right
In the transitional region that reinforcing plate rear end, reinforcing plate rear end are connected with reinforcing plate side, it is designed generally according to longeron trend, and
Longeron and threshold reinforcing plate are typically chosen high strength steel, therefore, are set by the transitional region connected in reinforcing plate both sides with rear end
Put for the First Transition flange with the welding of longeron inwall and the second transition flange for strengthening plate weld with threshold, strengthened
Reinforcing plate is connected by plate when installing using solder joint with chassis runner and threshold reinforcing plate, and such towing arm has more in carrying
Path of Force Transfer, be advantageous to the scattered transmission of load, the stress in the neighbouring metal plate region of mount point and solder joint can be reduced so that
Towing arm body mounts meet strength character requirement.
Further, the front end flange height is more than rear end flange height, the both sides bending extension of the front end flange
There is reinforcement wing plate.Due to the longitudinal impact force of the main bearing vehicle body of towing arm, thus by increasing the Z-direction of reinforcement front edge of board flange
Highly, and by strengthening wing plate and side cover plate and threshold strengthen plate weld, can meet it is light-weighted under the premise of increase and strengthen
The contact area of plate and side cover plate and threshold reinforcing plate, the whole support stiffness for strengthening front edge of board is improved, so as to lift towing arm
The intensity of mount point；Meanwhile front end flange constitutes the reinforcement harden structure similar to " L " type with mounting plane and rear end flange,
High degree adds the Y-direction intensity of towing arm mount point.
Further, the side flanging is provided with some towards automotive towing arm body stiffening panel outside along its length
Boss.By the setting of boss, the support of side cover plate and threshold reinforcing plate to whole reinforcing plate can be increased, lift towing arm
The intensity of mount point.
Further, length direction uniform gap of the boss along the side flanging is set, to ensure structural stability.
Further, the front end flange is provided with the reinforcement parallel with the body of a motor car width, with lifting
The intensity of front end flange.
Further, four bracket of trailing arm mount points of setting on the automotive towing arm body stiffening panel, described four
Bracket of trailing arm installs dot matrix arrangement.
Specifically, the automotive towing arm body stiffening panel integrated punching shaping.
